One of the finest specimens of this artistic industry is the splendid _reja_ which divides the nave at the royal chapel of Granada. Its immense size has enabled the artist to carry out a splendid ornamentation in the "plateresque style," combined with reliefs on a large scale of figures of apostles and saints, terminated at the upper part with a wide band of ornamentation of leaves and flowers, crowned with a Rood, with the Virgin and St. John on either side. The splendid balustrades and supports are forged with the hammer; the figures and circular piers are formed of large plates, _repoussé_ and carved in the most admirable manner, and give a good idea of the difficulties of this work, which the artists of this time had overcome, long before the various technical facilities of the present day existed. The ornamentation of this _reja_ was originally gilt, and the figures are painted in oils. It was made about the year 1520 to 1530; in the lock, formed as a Gothic pinnacle, is a small inscription, "Maestro Bartolome me fec." This same artist worked at Jaen and Seville. Cean Bermudez calls him "sculptor and iron-master." Two most important specimens of iron-work exist also at the cathedral of Toledo, enclosing the _Capilla Mayor_ and _Coro_. The _reja_ of the Capilla Mayor is 42 feet wide by 19 inches high; it rests on a pediment of marble ornamented with masks and bronze work, upon which rises the _reja_, which is divided horizontally by means of a frieze of ornamentation, and this again vertically in five compartments. In each vertical division there is a pilaster of four sides formed of _repoussé_ plates, carved with a fine ornamentation in the renaissance style, this is again terminated with life-size figures in high relief of bronze. The second compartment rises upon the band which divides it in an horizontal sense; it follows the same decoration in its pilasters, and is terminated by a series of coats of arms, torches, angels, and a variety of foliage which finishes the upper part. Upon the centre, hanging from a thick chain supported from the roof, is suspended a life-size Rood, of admirable effect, which completes the decoration. In several spots there are labels with mottos in Latin; in one of them appears the following inscription, and the date of 1548 when this splendid work was finished: "Anno MDXLVIII. Paul III. P. M. Carol. V. Imper. Rege. Joannes Martinez Siliccus. Archipiscopus. Tolet. Hispaniae. Primat." The railings of this _reja_ are silvered, and the reliefs and salient points gilt. The artist who made it was Francisco Villalpando, a native of Valladolid; this model was chosen among those of several artists, who presented their plans in competition before the ecclesiastical authorities; it is calculated that ten years elapsed before it was finally finished in 1548. Villalpando was greatly distinguished likewise as a sculptor and architect. In 1563 a book was printed after his death of a translation
